This does what it advertises. It's an extended battery and it does just that. I went from charging my phone once a day to once every 2 to 3 days, and when it comes to a smartphone more battery life is where its at. Would recommend, would buy again if needed.

I ordered this for my mothers phone, whose stock battery was on its way out. I might add that the stock battery was never sufficient for the phone to begin with. This one went-right in with the new back plate. I left it charging until it hit 100%. So far, so good. Holds a charge well, it is not getting unusually hot as what often happens with cheap batteries, and seems to be lasting far longer than the original one, even when it was new. For the price, this was an easy decision. I just wish it came with a custom plastic case. thanks tmart!
